RAILWAY DIAMOND AND OTHER CROSSINGS.

Patented Sept. 9, 1913.

Application filed July 1, 1910. Serial No. 569,879.

To all whom it may concern Be it known that we, CHARLES ALLAN Dronson, asubject of His Majesty King George V, Emperor of India, mining engineer,of Kodarma, Bengal, British India, and NOEL LINDSAY BURTON-J ONES, alsoa subject of His Majesty King George V, Emperor of India, mica-miner, ofTaraghatty, Bengal, British India, have invented Improvements in RailwayDiamond and other Crossings, of which the following is a full, clear,and exact specification.

This invention relates to improvements-in diamond and other crossings ofthe classin which a pivoted length of rail or two parallel rails, is orare arranged to pivot so as to form a continuation of the rail or railsat their point or points of intersection, the pivoted rail or railsbeing capable of being moved so as to form a continuation of eithertrack at the point or points of intersection; and more particularly toautomatic devices which when depressed by the flanges of the leadingwheels of a vehicle move the rail or rails over, and consists inimprovements whereby the number of moving parts is greatly reduced andthe workof fitting up is considerably lessened. I

In order that our invention may be readily understood reference will bemade to the accompanying drawings in which a convenient form of ourinvention may take is shown by way of example.

In these drawings :Figure 1 is a plan of the central section of adiamond crossing with automatic actuating and locking mechanism. Fig. 2is an enlarged side elevation of one of the cranks 16 and connections ofrocker rail 8. Fig. 3 is a plan of same.

Referringv now to Fig. 1, the central portion of a diamond crossingconsists of a turn-table of two rails 1 and 2 which are parallel andsuitably connected together such as by bars or the like 3 at each endand a central portion 4, such rails 1 and 2 and their connections beingpivoted on a pin or trunnion 5- and being capable of movement so thattherails 1 and 2 may be arranged to form a continuation of the track 6or of the track 7. In the position shown in the drawing they form acontinuation of the track 7 Running parallel with the rails and on theinside so as to be depressed by the flanges of the wheels are rails orangle irons S, 9, 10 and 11. Each of these rails is placed alongside theinner portion of the rail at an inclined angle being pivoted at theirlower ends which are farther from the center of the crossing, the bars 8and 9 being shown pivoted at 1.2 and 13 respectively. The upper end, thetop of which when not set for the particular track is flush with the topof the rail, has a slot 14 therein (Fig. 2) in which a pin 15 on thecranks 16 works. The cranks 16 are pivoted at 17 to the chairs (notshown) and the pins 15 work in slots 18 in the ends of the connectingrods 19, 20, 21 and 22 (Fig. 1) the other ends of which are pivoted at23 and 24 to the portion 4. The cranks 16 are all inclined from thevertical inward toward the turn-table. When, therefore, the flange of awheel comes in contact with one of the angle irons 8, 9, 10 or 11 itwill press it down and its crank 16 will move forward owing to the crankbeing set at an angle and when fully depressed will be in the positionshown by dotted lines in Fig. 2, the pin 15 moving in the slots 14- asshown. The movement of the crank is conveyed by the connecting rod 19,20, 21 or 22 to the turn-table which moves over so that the rails 1 and9 are set for the right track. The inner ends of the angle irons 8 and11 will be in the depressed position when the turn-table is set fortrack 7 and the angle irons 9 and 10 will be in their normal or raisedposition flush with the top of the rails, and the parts will remain inthis position until the track 6 is required when the flange of theleading wheel comes onto the angle iron 9 or 10 anddepresses it causingthe turn-table to shift over and both 9 and 10 to be depressedand theangle irons 8 and 11 to rise flush with the rails.

Although in the foregoing description we have described a centraldiamond section (Fig. 1) as having the rails 1 and 2 pivoted on a commoncentral pivot, it will be obvious that each rail may oscillate on itsown. pivot, suitable connections being provided for the purpose; andthat changes, variations and modifications may be made without departingfrom the general spirit of the invention. Suitable stops 11 have beenprovided to limit the movement of the pivoted. rail or rails.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be per formed, we declarethat what we claim is l. A railway switch, comprising rails of a maintrack and siding rails, a central portion pivoted to swing in ahorizontal plane rails upon such portion and adapted to be brought intoalinement with said rails, rails arranged vertically movable adjacent arail of each track to be engaged by a Wheel of vehicle traveling overthe same, horizontally movable actuating rods pivotally connected to thecentral portion at one end and formed each with a vertical slot at theother end, cranks pivoted at fixed points adjacent to said verticallymovable rails and movably connected to the same, and studs connected tosaid movable rails and cranks and vertically movable in the slots of theactuating rods. V

2. A railway switch, comprising rails of a main track and siding rails,a central portion pivoted to swing in a horizontal plane,

rails upon such portion and adapted to be brought into alinement withsaid rails, rails arranged vertically movable adjacent a rail 25 of eachtrack to be engaged by a wheel of a vehicle traveling over the same andformed with horizontal slots, horizontally movable actuating rodspivotally connected to the central portion at one end and formed each 30horizontal slots of the movable rails and the 35 vertical slots of theactuating rods.

In witness whereof we have hereunto set our hands in the presence of twowitnesses.
